What does an alcoholic beverage contain that is a central nervous system depressant?

Art [367]

Answer:

interferes with release of neural transmitter GABA

Explanation:

Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA

depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
